You are right. Audio amplifiers have not historically been power efficient. In the case of a headphone amplifier on AC power, we don't have to think about efficiency, as long as it isn't ridiculous, like drawing 100W. Class B amplifiers are only efficient when producing no output, or when producing output clipped to the power rails (like a square wave). Due to being almost fully off or fully on. For a sinusoidal sign…
Okay, since you appear to know what you're talking about, if I wanted to maximise signal reproduction (with absolutely zero consideration for efficiency) when matching amplifiers with speakers (for car audio), what numbers should I be looking at when choosing components? (Yes, I checked a few youtube videos and blogs, but car audiophiles don't really get too scientific and it's hard to tell whether they really know w…
What you want is low THD and low output impedance.

In audio, the speakers are much more important than the amplifier. You will not easily hear a difference between two good power amplifiers, but you can easily hear the difference between pretty much any two speakers.
As far as matching goes, you want amp power > speaker power handling. If the amp distorts before the speakers do, you're not getting the most out of the speakers, and clipping can be bad for some speakers too, especially tweeters.
Also, the THD figures quoted for amplifiers are usually at moderate output levels; they get worse with higher voltage swing. An amp that is getting close to clipping will generally have worse THD than one which is nowhere near clipping. (As well, THD gets worse with rising frequency.)

#114I find myself guilty of deep-diving into headfi-territory audiophilia once in a while, this time it got to me as well and I started thinking how neat it'd be to finally do it and get some high-end replacement for my 250 ohm dt990 pro cans, and I've heard both the hifman arya and sennheiser hd800s and know they are quite a lot better.. but THEN comes the amp question... and the rabbithole deepens.. and then the DAC an…
If you would just commit all the way and get an atomic clock you could save yourself from the tyranny of jitter in the 1MHz audio band and then it'd all be worth it.

> I guess what I hate about gear, is what others love, that there's no one right, no one truth, and that subjective experience has to be taken into account.. I don't want subjective, I want the objective truth, accurate reproduction.. but what is even that..
But you already found the objective truth: people experience it differently.
Maybe it's not the truth that you wanted but rather whatever that you wanted to be the truth
